10 Energy-Efficient Smart Gadgets Under $100
Let’s break down the best money-saving, easy-to-use devices you can add to your rental, today.
1. Smart LED Light Bulbs
Replace energy-sucking incandescents with smart LED bulbs. These last up to 25 times longer and use 75% less energy. Plus, you can:
- Control lights with your phone or voice assistant
- Set automated schedules (off when you’re at work)
- Adjust brightness for the right mood and efficiency
Brands like Philips Hue and Wyze offer bulbs under $20 each. Just screw them in—no wiring needed.
2. Smart Power Strips
Vampire power—energy used by devices in standby mode—can drain your wallet. Smart power strips stop the drain by:
- Cutting power to devices not in use
- Integrating with smart assistants (Alexa, Google Home)
- Letting you individually control sockets via mobile apps
Priced under $35, these pay for themselves in savings in no time.
3. WiFi Smart Plugs
Don’t want to replace every device? Add WiFi smart plugs (usually $10-$25 each) and transform any appliance into a smarter one. With smart plugs, you can:
- Turn devices on/off remotely (great for coffee makers, fans, lamps)
- Set schedules to eliminate unnecessary usage
- Monitor energy consumption for each device
Just plug them into any standard outlet. No tools or setup hassle!
4. Programmable Smart Thermostats (Plug-in Models)
Many renters assume they can’t upgrade the thermostat, but plug-in and portable thermostats are available—no wiring, no problem. These gadgets work with window AC units, electric radiators, and space heaters. Features include:
- Customizable heating/cooling schedules
- Smart learning for optimized temperatures
- Remote app control
Begin saving up to 10% on your heating and cooling bill for well under $100.
5. Smart Radiator Valves (Thermostatic)
If you rent in an older building with radiator heating, smart thermostatic radiator valves let you control each room individually—no landlord intervention needed. Benefits include:
- Room-by-room temperature control
- Built-in timers and scheduling
- Reduced energy waste in unused spaces
Most models are under $50, install easily, and can help cut bills during heating season.
6. Battery-Powered Motion Sensor Light Switches
Stop paying for lights left on all day. Stick-on, battery-powered motion sensor switches turn off lights automatically in unused rooms. Great for:
- Hallways and closets
- Bathrooms and laundry rooms
- Kitchens after midnight snacking
They’re renter-safe and cost around $15-$40 per room.
7. Smart Window Shades (Controller Kits)
Smart shades can be pricey, but starter kits are available for as little as $60. These DIY retrofits let you:
- Automate opening and closing based on sunlight
- Reduce heat gain in summer and heat loss in winter
- Schedule adjustments from your phone
Blocking out the heat during the day reduces AC usage, while trapping warmth at night saves on heat.
8. Energy Monitoring Smart Sensors
The first step to improving efficiency is knowing where you use the most energy. Plug-in energy monitors clip onto appliances or sockets and give you real-time usage stats right to your phone.
- Track inefficient devices
- Set usage alerts
- Discover phantom loads
Many are under $40 and require zero installation—just plug in and monitor.
9. Smart Leak Detectors
Water leaks can cause huge bills and damage, especially for renters. Smart leak detectors (usually $30-$50) alert your phone at the first sign of a leak. Use them near:
- Washing machines and water heaters
- Bathrooms and under sinks
- Dishwashers and refrigerators
Preventing leaks saves money and headaches, and some insurance companies offer discounts for having them.
10. Smart Fans (Plug-in, App-Controlled)
Moving air costs less than cooling it. Smart plug-in fans (or small portable models) can be controlled by app and integrate with smart plugs. Features include:
- Synchronized turning on/off with air conditioner cycles
- Scheduled airflow to reduce AC runtimes
- Remote adjustment via smartphone
Most are $30-$80—much cheaper than running the AC all day.
